Why cannot I allocate more than -Xmx700M

Uhm... You lost it? I know there is a problem with the intel  
architecture that the PCI address space is placed in the upper parts  
of the 4GB memory space, so if you have 4GB ram, only 3 is visible to  
the machine as actual memory. The rest is PCI. I have 4GB in my  
macbook pro and I have 3GB available to the OS.

What version of Java are you using? Linux/sun or native port?

I tried on a machine with 2GB physical RAM and one with 768MB of RAM  
and both let me allocate 1GB (-Xmx1G) just fine, buy not 2GB (-Xmx2G).  
This is using the native FreeBSD Java 1.6.0 port.
